A CAPTCHA (Completely Automated Public Turing test to tell Computers and Humans Apart) is a security measure using challenge-response authentication. This measure helps protect your account's spam and prevent decryption of password trying subjecting you to a simple test to verify that it is a human and not a computer that tries to access the account.
A CAPTCHA test consists of two parts: a random sequence of letters and/or numbers that appear in a distorted way, and a text box. To pass the test, simply enter the characters from the image into the text box.
Why is Google using CAPTCHA tests?
Google is committed to protecting your information. The CAPTCHA protects your digital remote access account so that only one user in flesh and bones with the appropriate password can access it. Indeed, if computers can create a distorted image and process the response, they can not read this image or solve the problem in the same way as a human being.
Of many Web services, like Google, use the CAPTCHA tests to prevent any unauthorized access to an account. You can find also on sites for accessing sensitive information, such as bank accounts.
